3.3.3 3A and EHEDG approval
To satisfy the sanitary requirements of the European Hygienic Engineering and Design Group,
when installing this meter you MUST give consideration to:
•
Installation - install the meter at an angle to allow self-draining (see illustration).
•
Cleaning fluids - cleaning fluids should flow uphill with a velocity rate greater than
1.5 m/s / 5 ft/s. If the process flow is downhill, install a flow restrictor downstream of the
meter. This will make sure that the meter is completely filled with the cleaning fluid.
•
Process connections and seals MUST be in accordance with EHEDG documentation.
The manufacturer also recommends that you refer to EHEDG (www.ehedg.org) document
number 8 "HYGIENIC EQUIPMENT DESIGN CRITERIA".
3.3.4 Flow direction
With the orientation of the meter as shown in the illustration (Lumberg
®
connector offset to the
right) the factory set flow direction is left to right.
If the meter has been intalled with the process flow running from right to left, the flow direction
can be changed through the supplied software Toolbox

1
Mount the meter vertically to allow self-draining.
2
If you are installing at an angle, the maximum offset angle for the meter to be self-draining is 12
°
.
3
DO NOT install the meter with an offset angle greater than 12
°
. This will prevent the meter from self-draining.
